ZBT SRAMs have been designed to optimize the performance of table access in networking applications.
This section describes how to interface to ZBT SRAMs.
is used to generate control signals. The same interfacing is used for pipelined and flow-through versions
of ZBT SRAMs. However different UPM patterns must be generated for those cases. Because ZBT
